This program was used to send sms by PIC18F452 and Wavecom GSM modem.It was successful.
void send_sms(){
const unsigned char para[5]="AT\r\n";
const unsigned char textmode[12]="AT+CMGF=1\r\n"; //select pdu mode (o is given ; 1 is given for text mode)

Hi,
I want to design a power supply for above modem. I tried with several ccts but not worked.
Specifications:
7.5v
600mA
If u have suitable power supply. Pls give me schematic diagram.
Thank you very much
Hi,
I want to periodically sleep the my PIC18f452. It gets sleep only first time.not again.
I think my program is incorrect.
I wake up pic by giving interrupt to RB1/INT pin
Can anyone guide me using programming example.
Thank You very much
Hi all,
I am using PIC18f452 to communicate with Wavecom 1306b modem. I used only RX,TX and GND pins. I can communicate with the modem using HyperTerminal with the use of only these three pins.
I am using MAX232 as logic level converter and checked the MAX232 Outputs also with PC. It was also...
We should take RX, TX nad GND pin of the phone. then it works. If you want you can use just a connector of the USB data cable to connect above three pins.
Just cutting USB head and connecting RX,TX will not work.
regrds,
Amila
Hello,
I am going to buy above modem before that I want to confirm that Is that modem support for Text mode.
If any one who have used this modem for above application please tell your comment about the modem.
Or can you recommend any other modem.
Thank you very much
Thank you very much for your reply. Because I used 10uf with MAX232. My application is send sms using pic and phone. But it didn't work. Without MAX232 it worked.
regards,
Amila
Hello,
I have seen MAX232 capacitor's different values in applications like 10uf, 1uf, .1 uf. I want to know how to select the accurate capacitor value for our application.
Can anyone clarify this for me please.
Thank You
Hi,
I want to know
whether the Wavecom1206b support for SMS text mode?
if there any one who have send sms using this modem and PIC through AT commands.
Please inform me.
Thank You very much
Yes, I have some example code.
int i=0;
int j=0;
int receive;
void main(){
// unsigned char *p ;
//unsigned char ok[5];
const unsigned char command1[5]="AT\n\r";
const unsigned char dial[17]="ATD0716530115;\n\r";
TRISB=0x00;
Usart_Init(9600)...
Hi,
I did it using MAX232. But it not works. Without MAX232 I can do all the commands successfully except sending SMS(in PDU mode).(Error is +CMS 304). I can send SMS using HyperTerminal not in PIC.
Thanx.
